Comparative Study[Evaluation of the influence of physical environmental factors on morbidity among armed forces personnel].
Under the conditions of hot and mountain-continental climate, the morbidity rates were estimated to be significantly lower than those in young men who had not been acclimatized or adapted to living conditions and in non-acclimatized men. A role of individual physical environmental factors (temperature, relative humidity, barometric pressure, average and maximum air speed) and integral exposure by the wind chill index (a combined impact of an air speed and ambient temperature) as risk factors to human health was defined. The mountain-continental climate showed a relationship of the influence of these factors to habitation at different altitudes.

[Physical factors of the urban dwelling environment: ecological and hygienic aspects].
The paper describes the ecological and hygienic significance of the physical factors of the urban dwelling environment: the macroclimate of a residential area, the microclimate within the residential and public buildings, the ionic ozone regimen of premises, an electromagnetic load on the population, the problems associated with noise and light exposure. It also gives an integrated assessment of the current air-conditioning systems, household electric appliances, and building engineering systems. A system of measures is proposed to optimize the quality of the urban dwelling environment.

[Physical factors of the industrial environment and traffic safety].
The paper deals with the problem of optimization of working conditions of engine drivers in the control cabs of up-to-date locomotives, by toughening the sanitary-and-hygienic requirements for the levels of bad industrial factors. The authors associate the optimization of working conditions with the necessity of strengthening the reliability of their driving activity due to the increasing rail movement speeds and the transfer to one-person rolling-stock operation, and other factors.

Comparative Study[Comparative hygienic evaluation of the interenvironmental distribution of trace elements in the environment].
The paper presents the results of long-term monitoring of the content and interenvironmental distribution of the chemical elements Ni, Cd, Pb, Cr, Cu, Zn, Fe, and Mn over 1993-2007 in the environmental objects. The studies were made in the urbanized and rural areas of the Orenburg and Orsk-Troitsk industrial centers. General regularities were found in the quantitative distribution and priority relationships of the elements in the drinking water, in the atmosphere of residential areas (snow cover), in soil, foodstuffs, and children's biomedia.

Review[The chemical and trace element composition of water sources in the Orenburg Region].
The chemical composition of drinking water was studied by some indices: total mineralization, oxidability, harshness by different regional economic areas of an angoindustrial region. The content of trace elements, imbalance of which had been found by earlier studies, was determined. Higher water mineralization was ascertained in the central area, higher water harshness and oxidability were in the eastern area. The areas under study showed the inhomogeneous content of trace elements.
